Might be a little late in the year for feedback on the summer gloves, but I'll give two thumbs up on the Airvolution gloves.

I typically wear a small or size 8 glove, but I've had to go with a Medium on some thicker Rev'it gloves. The Airvolution gloves are closer fitting, so I went with a small. The first couple of days that I wore them I was a little worried that they were too small, but now I've put a few thousand miles on them and they are my first-choice glove. They have broken in to a nice custom-fit.
I haven't crash tested them yet, but I'll see what I can do about that and I'll get back to you.
